ABB 液位变送器LMT200E2S6R1B1D3L2H1CSR5规格描述

ABB 液位变送器LMT200系列简介

MT200 基于磁致伸缩原理。

1. 设备电子元件以固定间隔产生低能电流脉冲。

2. 电脉冲产生磁场，该磁场沿传感器管内的专用导线传播。

3. 导线和磁性浮子周围的磁场相互作用导致导线中产生扭转应力波。该扭转以已知速度沿导线传播，从磁性浮子的位置开始，向导线的两端传播。

4. 发射器组件中放置的专利传感元件将接收到的机械扭转转换为电返回脉冲。

5. 基于微处理器的电子元件测量起始脉冲和返回脉冲之间的经过时间（飞行时间），并将其转换为与浮子液位成比例的位置测量值。

The LMT200 is based upon the magnetostrictive principle.

1. The device electronics generates a low energy current pulse at fixed intervals.

2. The electrical pulses create a magnetic field which travels down a specialized wire inside the sensor tube.

3. The interaction of the magnetic field around the wire ａnd the magnetic float causes a torsional stress wave to be induced in the wire. This torsion propagates along the wire at a known velocity, from the position of the magnetic float ａnd toward both ends of the wire.

4. A patented sensing element placed in the Transmitter assembly converts the received mechanical Torsion into an electrical return pulse.

5. The microprocessor-based electronics measures the elapsed time between the start ａnd return pulses (Time of Flight) ａnd converts it into a position measure- ment which is proportional to the level of the float.
